Abstract

The relationships of the yellow-pigmented hydrogen-oxidizing species , and ,” which are all members of the acidovorans ribosomal ribonucleic acid (rRNA) complex in rRNA superfamily III, were studied by using deoxyribonucleic acid (DNA):rRNA hybridization, immunotyping, numerical analysis of biochemical and auxanographic features, polyacrylamide gel electrophoresis of cellular proteins, numerical analysis of fatty acid patterns, and DNA:DNA hybridization. Our results show that these five yellow-pigmented hydrogen-oxidizing species are more closely related to each other than to other taxa belonging to the acidovorans rRNA complex. We propose the transfer of these species to a new genus, , with the following four species: (formerly ), (to accommodate both and (formerly ), and (formerly ). The type species is , with monotype strain DSM 619 (= LMG 2185 = CCUG 1658). Because grows slowly and unreliably, but is genotypically and protein electrophoretically very similar to , the latter species can be used as an alternative reference taxon for the new genus. The type strains of , and are strains GA3 (= LMG 5945 = CCUG 13799). DSM 2082 (= LMG 7170 = CCUG 15921), and Stanier 362t1 (= LMG 2366t1 = CCUG 20334), respectively.
